If somebody

How do you think if somebody from forums will find, create some wining method - do others will know that or can be a long time that others even not heard about such?
So in simple words how long can some wining method exist without being heard for others…?

others can not discover the winning method from the first. if method is something new . if is more of the same maybe in other part are people winning with the same.if is something new and good it has more chances to be discovered from casino and not from other player.
